Abstract:
The screening of active components of traditional Chinese medicine has always been the focus and difficulty in modern research of Chinese medicine preparations. With the continuous development of life science, omics and computer technology, the virtual screening technology for active components of traditional Chinese medicine has gradually come into people's vision. Molecular docking technology is an important method for screening active components of traditional Chinese medicine. It not only has a short cycle and strong operability, but also avoids the disadvantage of poor stability in pharmacological experiments. Safflower extract can effectively alleviate the symptoms of myocardial ischemia, but its active components are not clear. In this study, with use of the molecular docking technology, the active components in safflower against myocardial ischemic were virtually screened based on the screening method of active components. Forty-six chemical components and 5 target proteins which showed high correlation with myocardial ischemia were obtained from the existing database and related literature reports. With the molecules of three commercially available drugs diltiazem, trimetazidine and verapamil as positive control molecules, the compomnents were docked with 5 target proteins. Active components were screened according to docking scores and interactions between molecules and targets, and then the active ingredients can be inferred. Fourteen chemical components were screened to have the most potential anti-myocardial ischemic activity, and all of them were flavonoids. Therefore, it can be inferred that the flavonoid components are the most potential anti-myocardial ischemic components in safflower. The screening of active anti-myocardial ischemia components in safflower was completed in this study, laying the foundation for subsequent researches.
